Perhaps I am misunderstanding what can and cannot be represented, but the DAG matters a lot to some of us. Consider:
Cellular organisms Archaea Bacteria Eukaryotes Animals Vertebrates Invertebrates Plants Fungi etc. These are not correct taxonomy terms, but just for example. How would these be represented? With categories, it's straightforward. I don't see how a flat tag intersection does this.
I don't think there are any plans to remove subcategory functionality. Only unnecessarily specific categories will be ditched, presumably, that logically consist of nothing more or less than an intersection of other categories. Categories like "Plants" don't, so they'd stay.
